Power Plugs and Voltage in China: What You Need to Know
China uses Type A, Type I, and Type C sockets at 220V/50Hz. Most modern devices handle the voltage, but socket compatibility varies. Here is what to pack and what to buy when you arrive.

Electricity in China runs at 220 volts and 50 hertz. This matters because it determines which of your devices will work safely and which require adaptation. The good news is that most modern travel electronics are designed for the full international voltage range. The bad news is that some common household items — particularly North American ones — are not, and plugging them in directly causes immediate failure.
Voltage: the fundamental issue
**Dual-voltage devices** (input 100–240V, 50/60Hz): these work globally with only a plug adaptor — no converter required. This includes the large majority of modern consumer electronics: - Laptop chargers (check the fine print on the brick) - Smartphone chargers - Camera and action camera chargers - Tablet chargers - USB charging hubs - E-readers - Most electric toothbrush chargers
To confirm your device is dual-voltage, look at the label on the charger or power supply. If it says "Input: 100-240V" or "100V-240V~", it handles both the North American 110V and the Chinese/European 220V. You need only a plug adaptor, not a converter.
**Single-voltage devices** (input 110V or 120V only): these require a voltage converter when used in China, or replacement: - North American hair dryers and hair straighteners - Some older electric shavers - Some kitchen appliances brought from North America - Older power tools
Plugging a 120V-only device directly into a 220V socket does not simply produce a weaker result — it typically destroys the device immediately, sometimes with smoke. This is an irreversible error. Check the label before plugging in.
Plug types: what fits where
China's standard wall socket (GB/T 1002) is designed to accept multiple international plug types in a single socket format. A standard Chinese socket has:
- Two flat vertical slots (left wider, right narrower): accepts North American Type A plugs
- Two diagonal slots (angled apart at roughly 30°): accepts Australian and Chinese-standard Type I plugs
- Two round slots: accepts European Type C plugs
The three slot types are arranged to overlap in one socket, so a single socket accepts all three without adaptors. Many modern Chinese sockets are of this universal type, particularly in hotels and newer buildings.
North American Type A (two flat parallel pins): fits directly into the flat vertical slots of a standard Chinese socket. Many North American travellers find their phone charger works without any adaptor — simply plug it in and check if the voltage range is compatible.
European Type C (two round pins): fits the round slots in the Chinese socket. No adaptor required.
UK Type G (three rectangular pins in a triangular arrangement): does not fit Chinese sockets. Requires an adaptor.
Australian Type I (two flat pins angled in a V shape): fits the diagonal slots in the Chinese socket. No adaptor required.
Swiss Type J: not compatible; adaptor required.
In older buildings, hotel rooms with renovation gaps, or rural areas, you may encounter sockets that only accept one or two plug types. Having a universal travel adaptor as a backup handles these situations.
USB charging
Most hotels in China (at all levels above budget backpacker) now provide USB-A or USB-C charging ports at the bedside or desk in addition to standard sockets. For travellers whose primary need is charging smartphones and tablets, these ports reduce the adaptor problem significantly — a USB cable from any country works without adaptation.
What to pack
From North America: a plug adaptor is useful insurance but many Type A chargers fit directly. Confirm voltage before packing appliances like hair dryers — either leave them, or buy a travel version specifically rated 100–240V. A 220V-compatible travel hair dryer is widely available.
From the UK: a UK-to-Type A or UK-to-Type C adaptor is required. Or a universal travel adaptor.
From Australia: no adaptor required for standard devices; the diagonal slot accepts Type I directly.
From Europe: no adaptor required for standard Type C devices.
Buying adaptors and converters in China
Universal travel adaptors are available at airport shops, electronics markets (such as Zhongguancun in Beijing or Huaqiangbei in Shenzhen), supermarkets, and hardware stores. Prices are low. If you realise on arrival that you need an adaptor, it is an easy problem to solve — the airport departures area shops typically stock them.
Voltage converters (for 110V appliances) are available at electronics markets but are bulkier and heavier than adaptors. For most purposes, replacing the appliance with a locally purchased or travel-rated version is more practical than bringing a converter.
Power cuts and voltage fluctuations
Power supply in major Chinese cities is reliable. Significant voltage fluctuations are uncommon in urban areas, and power cuts during normal weather are rare in Beijing, Shanghai, Guangzhou, and other Tier 1 cities. In rural areas, typhoon season (June–October) can cause occasional outages in coastal provinces.
